Gary Cooper is an English conductor and classical keyboardist (most notably the harpsichord and fortepiano.) He is particularly known as an interpreter of the keyboard music of Bach and Mozart, and as a conductor of historically informed performances of music from the Renaissance, Baroque, Classical and Romantic periods.

Gary Cooper studied organ and harpsichord at Chetham's School of Music, the John Loosemore Centre, and was an organ scholar at New College, Oxford, where he graduated with First Class Honours. In 1990 while still a student at Oxford, he co-founded the New Chamber Opera, and has conducted many of their performances, including a complete recording of Jean-Philippe Rameau's cantatas and a new production of Handel's rarely performed opera, Orlando, at Sadler's Wells Theatre in 2006. Between 1992 and 2000, he was a member of the baroque ensemble, Trio Sonnerie, with whom he performed regularly throughout Europe and the United States.

Cooper made his Wigmore Hall solo recital debut on 1 December 2000 with a performance of Bach's complete Well-Tempered Clavier, and has frequently appeared as a recitalist both in the UK and in Europe. Several of his performances have been broadcast on BBC Radio 3, including his 22 November 2004 recital at the Cosmo Rodewald Concert Hall in Manchester and his 29 January 2006 Wigmore Hall performance of Mozart's sonatas for piano and violin with violinist Rachel Podger, broadcast live as part of the European Broadcasting Union's Mozart Day.

Gary Cooper has conducted for many ensembles including, the Akademie für Alte Musik Berlin, Irish Baroque Orchestra, Hanover Band, and English Touring Opera (Mozart's Die Entführung aus dem Serail and Handel's Alcina). He also teaches harpsichord and fortepiano at the Royal Welsh College of Music and Drama and the Birmingham Conservatoire, and is Visiting Professor of fortepiano at the Royal College of Music.
